Charles Calomiris in NYC – Medium-Term Downside Risk: Insights from Textual Analysis of News
The future of systemic risk modeling will combine quantitative data and textual analysis to forecast medium-term risks. We develop a classification methodology for the context and content of news articles to predict risk and return in stock markets in 51 developed and emerging economies. A parsimonious summary of news, including topic-specific sentiment, frequency, and unusualness of word flow, predicts future country-level returns, volatilities, and drawdowns. Economic and statistical significance are high and larger for year-ahead than monthly predictions. The effect of news measures on market outcomes differs by country type and over time. News stories about emerging markets contain more incremental information. Out-of-sample testing confirms the efficacy of our approach for forecasting country-level market outcomes.
